Abstract
Description
- The present invention is related to a driving mechanism, a protection device and a control method for a furniture system.
-
US patent number US 8,172,345 B2 discloses a self-moving device for movable furniture parts capable of assisting a drawer at a close position in opening relative to a cabinet (so-called push-open function), and capable of assisting the drawer in self-closing during an end process of the drawer moving from an open position to a retracted position (so-called self-close function). In addition,US patent number US 8,308,251 B2 also discloses a design capable of adjusting push-open strength. The two cases are provided for reference. - However, when a force applied by a user for closing the drawer from the open position is too strong or the user continues applying the force to push the drawer to move into the cabinet without stopping, the drawer may be further moved to an over-push position after being moved to the close position, such that the drawer is opened again (due to the design of push-open). In order to solve such problem, the present invention is provided.
- This in mind, the present invention aims at providing a driving mechanism, a protection device and a control method for a furniture system.
- This is achieved by a driving mechanism according to
claim 1, a protection device according to claim 9, and a control method according to claim 16. The dependent claims pertain to corresponding further developments and improvements. - As will be seen more clearly from the detailed description following below, the claimed driving mechanism is applicable to a first furniture part and a second furniture part. The driving mechanism comprises an open elastic member, an actuating member, and a protection device. The open elastic member is configured to provide an opening force when the second furniture part is moved relative to the first furniture part from a close position to an over-push position along a first direction, in order to drive the second furniture part to move to an open position along a second direction opposite to the first direction. The protection device is configured to interact with the actuating member. The protection device comprises a base, a blocking member, a control member and an elastic member. The blocking member is mounted to the base and movable between a first state and a second state relative to the base. The control member is mounted to the base and movable between a first control state and a second control state relative to the base. The elastic member is configured to provide an elastic force to the control member and the blocking member. Wherein, during a process of the second furniture part being moved relative to the first furniture part from the open position to the close position along the first direction, the actuating member is configured to drive the control member to move from the first control state to the second control state, and the blocking member is driven by the control member to move from the first state to the second state to be blocked by the actuating member, in order to prevent the second furniture part from being moved from the close position to the over-push position. Wherein, when the control member is moved from the second control state to the first control state, the blocking member is driven by the elastic member to move from the second state to the first state without being blocked by the actuating member, in order to allow the second furniture part to be moved from the close position to the over-push position.
- As will be seen more clearly from the detailed description following below, the claimed protection device is applicable to a furniture system. The protection device comprises a base, a blocking member, a control member and an elastic member. The blocking member is mounted to the base and movable between a first state and a second state relative to the base. The control member is mounted to the base and movable between a first control state and a second control state relative to the base. The elastic member is configured to provide an elastic force to the control member and the blocking member. Wherein, during a process of the protection device being moved relative to an actuating member of the furniture system from a predetermined position to a close position along a predetermined direction, the actuating member is configured to drive the control member to move from the first control state to the second control state, and the blocking member is driven by the control member to move from the first state to the second state to be blocked by the actuating member, in order to prevent the protection device from being moved relative to the actuating member from the close position to an over-push position along the predetermined direction. Wherein, when the control member is moved from the second control state to the first control state, the blocking member is driven by the elastic member to move from the second state to the first state without being blocked by the actuating member, in order to allow the protection device to be moved relative to the actuating member from the close position to the over-push position along the predetermined direction.
- As will be seen more clearly from the detailed description following below, the claimed control method is applicable to a furniture system. The furniture system comprises a first furniture part, a second furniture part and an open elastic member. The second furniture part is configured to be moved relative to the first furniture part from a close position to an over-push position along a first direction, in order to allow the open elastic member to release an opening force to drive the second furniture part to move to an open position along a second direction opposite to the first direction. The control method comprises: providing a blocking member and a control member mounted to a base, the blocking member being movable between a first state and a second state relative to the base, the control member being movable between a first control state and a second control state relative to the base; providing an actuating member; moving the blocking member from the first state to the second state to be blocked by the actuating member when the second furniture part is moved from the open position toward the close position along the first direction, in order to prevent the second furniture part from being moved from the close position to the over-push position; and moving the blocking member from the second state to the first state without being blocked by the actuating member a period of delay time after the actuating member drives the control member to move from the second control state to the first control state, in order to allow the second furniture part to be moved from the close position to the over-push position.

FIG. 1 andFIG. 2 are diagrams showing afurniture system 20 comprising afirst furniture part 22 and asecond furniture part 24 longitudinally movable relative to thefirst furniture part 22 according to an embodiment of the present invention. In the present embodiment, thefirst furniture part 22 is a first rail (such as a fixed rail), and thesecond furniture part 24 is a second rail (such as a movable rail). Furthermore, the first rail is fixedly mounted to acabinet 22a (the first rail and thecabinet 22a can be seen as one component), and the second rail is configured to carry adrawer 24a (the second rail and thedrawer 24a can be seen as one component). However, in other embodiments, thefirst furniture part 22 and thesecond furniture part 24 are not limited thereto. - As shown in
FIG. 3 , thesecond furniture part 24 is in a retracted state relative to thefirst furniture part 22. Thefurniture system 20 further comprises adriving mechanism 26. Preferably, thedriving mechanism 26 is arranged on one of thefirst furniture part 22 and thesecond furniture part 24. In the present embodiment, thedriving mechanism 26 is attached to thesecond furniture part 24, but the present invention is not limited thereto. - As shown in
FIG. 4 andFIG. 5 , thedriving mechanism 26 comprises afirst component 28, asecond component 30, an openelastic member 32, aprotection device 34, a recoveryelastic member 36 and an actuatingmember 52. Preferably, thedriving mechanism 26 further comprises a supportingmember 54. The supportingmember 54 and the actuatingmember 52 are movable relative to each other. - The
first component 28 and thesecond component 30 are movable relative to each other. For example, one of thefirst component 28 and thesecond component 30 has a guidingstructure 38. The guidingstructure 38 can be a bounded and longitudinally elongated hole. Wherein, a connecting member 40 has at least one connectingpart 42 penetrating through a portion of the longitudinally elongated hole, in order to mount thesecond component 30 to thefirst component 28, and allow thesecond component 30 and thefirst component 28 to be longitudinally movable relative to each other. Preferably, thefirst component 28 comprises a mountingbase 44. The mountingbase 44 comprises afirst control part 46. Thefirst control part 46 has a firstlongitudinal section 48a and afirst bending section 48b communicated with the firstlongitudinal section 48a and bent relative to the firstlongitudinal section 48a. On the other hand, the second component 39 is movable in one of the firstlongitudinal section 48a and thefirst bending section 48b through anengaging feature 50. The engagingfeature 50 can be an engaging pin. - The open
elastic member 32 is elastically connected between thefirst component 28 and thesecond component 30. Thesecond component 30 has a first abuttingpart 56 located at a position corresponding to a secondabutting part 58 of the supportingmember 54. - The
protection device 34 is configured to interact with the actuatingmember 52. Theprotection device 34 comprises a blockingmember 53 and acontrol member 55. Preferably, theprotection device 34 further comprises abase 57 for mounting the blockingmember 53 and thecontrol member 55. Thebase 57 is attached to thefirst component 28. For example, thebase 57 is fixedly mounted to thefirst component 28. - The recovery
elastic member 36 is elastically connected between the actuating member 52 (and/or the supporting member 54) and thesecond component 30. - Preferably, the
driving mechanism 26 further comprises a dampingdevice 59. The dampingdevice 59 is attached to thefirst component 28. For example, the dampingdevice 59 is fixed to thefirst component 28, and the dampingdevice 59 is adjacent to thebase 57. - As shown in
FIG. 6 andFIG. 7 , in addition to thefirst control part 46, the mountingbase 44 of thefirst component 28 further comprises asecond control part 60. Thesecond control part 60 and thefirst control part 46 are spaced from each other. Specifically, thesecond control part 60 has a secondlongitudinal section 62a and asecond bending section 62b communicated with the secondlongitudinal section 62a and bent relative to the secondlongitudinal section 62a. On the other hand, the actuatingmember 52 and the supportingmember 54 are pivoted to each other by a pivoting feature 64 (such as a pin member). Preferably, the supportingmember 54 has at least one first supportingleg 66, and the at least one first supportingleg 66 is located at a position corresponding to the secondlongitudinal section 62a of thesecond control part 60. On the other hand, the actuatingmember 52 has a second supportingleg 68, and the second supportingleg 68 can be located at a position corresponding to the secondlongitudinal section 62a of thesecond control part 60. Preferably, the actuatingmember 52 comprises afirst guiding feature 70 and a blockingfeature 72 separated from each other. In the present embodiment, thefirst guiding feature 70 can be a protrusion, and the blocking feature can be a wall with a predetermined height. Preferably, the actuatingmember 52 further comprises a catchingpart 74. For example, the catchingpart 74 is a hook. - As shown in
FIG. 8 and FIG. 9 , the blockingmember 53 and thecontrol member 55 of theprotection device 34 are movable relative to thebase 57. In the present embodiment, the blockingmember 53 and thecontrol member 55 are pivoted to thebase 57 by ashaft member 76. Preferably, theprotection device 34 further comprises anelastic member 78 configured to provide an elastic force to the blockingmember 53 and thecontrol member 55. For example, theelastic member 78 has a windingpart 80, and a firstelastic part 82 and a secondelastic part 84 respectively located at two sides of the windingpart 80. In addition, the firstelastic part 82 and the secondelastic part 84 are respectively mounted to the blockingmember 53 and thecontrol member 55. - The blocking
member 53 comprises a blockingpart 86. Preferably, one of the blockingmember 53 and thebase 57 comprises at least oneaccommodating room 88. In addition, the other one of the blockingmember 53 and thebase 57 comprises at least onerib 90. The at least oneaccommodating room 88 is configured to accommodate the at least onerib 90, and the at least one accommodating room is larger than the at least one rib90. In the present embodiment, the blockingmember 53 comprises the at least oneaccommodating room 88, and thebase 57 comprises the at least onerib 90. Preferably, the driving mechanism further comprises an abuttingmember 92 mounted to thebase 57, and an auxiliaryelastic member 94 configured to provide an elastic force to the abuttingmember 92. Specifically, thebase 57 has a mounting space S configured to accommodate the auxiliaryelastic member 94, and the abuttingmember 92 can be partially extended out of the base 57 through the elastic force of the auxiliaryelastic member 94. - The
control member 55 comprises asecond guiding feature 96. Specifically, thesecond guiding feature 96 is a passage. The passage comprises aninclined section 98a and alinear section 98b communicated with theinclined section 98a. In the present embodiment, theinclined section 98a is bent relative to thelinear section 98b, and thelinear section 98b is longitudinally arranged. Preferably, thecontrol member 55 further has an inclined surface or an arc surface. In the present embodiment, thecontrol member 55 has aninclined surface 100, but the present invention is not limited thereto. - As shown in
FIG. 10 , theaccommodating room 88 of the blockingmember 53 of theprotection device 34 is configured to accommodate therib 90, and theaccommodating room 88 is filled with a damping material L. (InFIG. 10 to FIG. 13 , the damping material L is shown as a plurality of black dots.) For example, the damping material L can be liquid or oil. Preferably, theelastic member 78 provides an elastic force to the blockingmember 53 and thecontrol member 55. Furthermore, the blockingmember 53 is in a first state S1 relative to thebase 57, and thecontrol member 55 is in a first control state C1 relative to thebase 57. - As shown in
FIG. 11 , when a force F is applied to thecontrol member 55, thecontrol member 55 is rotated relative to the base 57 to move from the first control state C1 to a second control state C2. On the other hand, the blockingmember 53 is driven to rotate from the first state S1 to a second state S2 in response to thecontrol member 55 being moved to the second control state C2. In the meantime, theelastic member 78 accumulates an elastic force. - As shown in
FIG. 11, FIG. 12 and FIG. 13 , when the force F applied to thecontrol member 55 no longer exists, thecontrol member 55 returns to the first control state C1 from the second control state C2 in response to the elastic force of theelastic member 78. Furthermore, during a process of thecontrol member 55 returning to the first control state C1 from the second control state C2, since theaccommodating room 88 of the blockingmember 53 is filled with the damping material L, motion of the blockingmember 53 moving from the second state S2 to the first state S1 is slowed down. In other words, the elastic force of theelastic member 78 applied to the blockingmember 53 is mitigated. - As shown in
FIG. 14 and FIG. 15 , when an external force F1 is applied to the abuttingmember 92, the abuttingmember 92 can be retracted into the mounting space S of the base 57 to push the auxiliaryelastic member 94, such that the auxiliaryelastic member 94 accumulates an elastic force. - As shown in
FIG. 15 and FIG. 16 , when the external force F1 no longer exists, the abuttingmember 94 can partially extend out of the base 57 once again in response to the elastic force of the auxiliaryelastic member 94. - As shown in
FIG. 17 , when thesecond furniture part 24 of thefurniture system 20 is located at a close position R relative to the first furniture part 22 (that is, thedrawer 24a is located at the close position R relative to thecabinet 22a), the actuatingmember 52 is configured to catch or engage with a fixed object 102 (such as a fixed pin) of thefirst furniture part 22 through the catchingpart 74. On the other hand, thesecond component 30 is configured to engage with thefirst bending section 48b of thefirst control part 46 of the mountingbase 44 through the engaging feature 50 (FIG. 17 only shows theengaging feature 50 for presenting a position of the second component 30), in order to temporarily hold the openelastic member 32 to accumulate an opening force. Furthermore, the first supportingleg 66 of the supportingmember 54 and the second supportingleg 68 of the actuatingmember 52 are respectively located within the secondlongitudinal section 62a of thesecond control part 60. A dampingrod 104 of the dampingdevice 59 is retracted relative to acylinder 106. - As shown in
FIG. 17 andFIG. 18 , a user can push thesecond furniture part 24 to move relative to thefirst furniture part 22 from the close position R to an over-push position P along a first direction D1 (that is, thedrawer 24a is located at the over-push position P relative to thecabinet 22a). When thesecond furniture part 24 is located at the over-push position P relative to thefirst furniture part 22, the openelastic member 32 is configured to provide the opening force. Preferably, the engagingfeature 50 is disengaged from thefirst bending section 48b of thefirst control part 46 of the mountingbase 44 to enter the firstlongitudinal section 48a, so as to allow the openelastic member 32 to release the opening force. - As shown in
FIG. 18 andFIG. 19 , after the openelastic member 32 provides the opening force, thesecond furniture part 24 can be moved relative to thefirst furniture part 22 to an open position E along a second direction D2 opposite to the first direction D1 in response to the opening force (that is, thedrawer 24a is located at the open position E relative to thecabinet 22a). Wherein, the second supportingleg 68 of the actuatingmember 52 further enters thesecond bending section 62b through the secondlongitudinal section 62a of thesecond control part 60, such that the actuatingmember 52 is deflected relative to the supportingmember 54 to engage with thesecond bending section 62b, and the recoveryelastic member 36 temporarily accumulate a closing force accordingly. Wherein, the catchingpart 74 of the actuatingmember 52 is detached from the fixedobject 102 of thefirst furniture part 22 due to the actuatingmember 52 being deflected. In addition, the dampingrod 104 of the dampingdevice 59 extends out of thecylinder 106 to be in a damping ready state. Preferably, the dampingrod 104 of the dampingdevice 59 faces toward the actuatingmember 52 and/or the supportingmember 54. - As shown in
FIG. 20 , when thesecond furniture part 24 is located at the open position E relative to thefirst furniture part 22, thedriving mechanism 26 is located at the open position E with thesecond furniture part 24. Wherein, the catchingpart 74 of the actuatingmember 52 is detached from the fixedobject 102 of thefirst furniture part 22. In addition, the dampingrod 104 of the dampingdevice 59 extends out of thecylinder 106 to face toward the actuatingmember 52. - As shown in
FIG. 20 andFIG. 21 , during an end process of thesecond furniture part 24 being moved relative to thefirst furniture part 22 from the open position E to a position close to the close position R along the first direction D1, the actuatingmember 52 can catch the fixedobject 102 of thefirst furniture part 22 once again through the catchingpart 74. As such, the actuatingmember 52 is deflected due to the second supportingleg 68 is moved from thesecond bending section 62b of thesecond control part 60 to the secondlongitudinal section 62a, in order to allow the recoveryelastic member 36 to release the closing force. - Furthermore, the actuating
member 52 and thecontrol member 55 are movable relative to each other. In the present embodiment, since the actuatingmember 52 is temporarily fixed due to the catchingpart 74 catching the fixedobject 102 of thefirst furniture part 22, the recoveryelastic member 36 releases the closing force to thesecond furniture part 24 during the end process of thesecond furniture part 24 being moved relative to thefirst furniture part 22 toward the close position R. Wherein, due to thesecond furniture part 24 being moved toward the close position R, thebase 57, thecontrol member 55 and the blockingmember 53 of theprotection device 34 can be moved relative to the actuatingmember 52 from a predetermined position X along the first direction D1. In other words, thecontrol member 55 and the actuatingmember 52 can be getting closer to each other. In such process, the actuatingmember 52 contacts thecontrol member 55, and the dampingrod 104 of the dampingdevice 59 abuts against the actuatingmember 52, such that the dampingrod 104 is retracted into thecylinder 106 to provide a damping effect. - As shown in
FIG. 22 , when the actuatingmember 52 catches the fixedobject 102 of thefirst furniture part 22 and thecontrol member 55 is moved close to the actuatingmember 52 along the first direction D1, the actuatingmember 52 contacts thecontrol member 55. Preferably, thefirst guiding feature 70 of the actuatingmember 52 contacts theinclined surface 100 of thecontrol member 55, in order to guide thefirst guiding feature 70 of the actuatingmember 52 to enter thesecond guiding feature 96 of thecontrol member 55. Wherein, the blockingmember 53 is in the first state S1 relative to thebase 57, and thecontrol member 55 is in the first control state C1 relative to thebase 57. Preferably, through thefirst guiding feature 70 of the actuatingmember 52 contacting theinclined surface 100 of thecontrol member 55, thecontrol member 55 is driven to move to be no longer in the first control state C1. - As shown in
FIG. 22 andFIG. 23 , when thecontrol member 55 is further moved close to the actuatingmember 52 along the first direction (that is, during the process of thesecond furniture part 24 being moved relative to thefirst furniture part 22 to the close position R along the first direction D1), thesecond guiding feature 96 of thecontrol member 55 interacts with thefirst guiding feature 70. Specifically, thefirst guiding feature 70 of the actuatingmember 52 is guided to enter theinclined section 98a of thesecond guiding feature 96 of thecontrol member 55, such that thecontrol member 55 is driven by the actuatingmember 52 to move from the first control state C1 to the second control state C2. The blockingmember 53 is further moved from the first state S1 to the second state S2 in response to thecontrol member 55 being moved from the first control state C1 to the second control state C2. In the present embodiment, thefirst guiding feature 70 is a protrusion, and thesecond guiding feature 96 is a passage. However, in other embodiments, thefirst guiding feature 70 can be a passage, and thesecond guiding feature 96 can be a protrusion, but the present invention is not limited thereto. - As shown in
FIG. 23 andFIG. 24 , when thecontrol member 55 is further moved closer to the actuating member 52 (that is, during the process of thesecond furniture part 24 being moved relative to thefirst furniture part 22 to the close position R along the first direction D1), thefirst guiding feature 70 of the actuatingmember 52 enters thelinear section 98b of thesecond guiding feature 96 of thecontrol member 55 from theinclined section 98a, and thecontrol member 55 can return to the first control state C1 from the second control state C2 in response to the elastic force of theelastic member 78. Wherein, when the blockingmember 53 is in the second state S2, and the control member 55 (and the blockingmember 53 and the base 57) is moved relative to the actuatingmember 52 to a close position R' (thesecond furniture part 24 can be seen to be located at the close position R), the blockingfeature 72 of the actuatingmember 52 is located at a position corresponding to the blockingpart 86 of the blockingmember 53 to block the blockingmember 53, in order to prevent the control member 55 (and the blockingmember 53 and the base 57) from being further moved relative to the actuatingmember 52 from the close position R' to an over-push position P' along the first direction D1. In other words, thesecond furniture part 24 is prevented from being moved from the close position R to the over-push position P. As such, the openelastic member 32 can be prevented from releasing the opening force. - As shown in
FIG. 24 andFIG. 25 , the blockingmember 53 is driven by the elastic force of theelastic member 78 to move from the second state S2 to the first state S1 a period of delay time after thecontrol member 55 is moved to the first control state C1. Preferably, a gap G is formed between the blockingfeature 72 of the actuatingmember 52 and the blockingpart 86 of the blockingmember 53 for assisting the blockingmember 53 in moving from the second state S2 to the first state S1. When the blockingmember 53 is in the first state S1, the blockingfeature 72 of the actuatingmember 52 is no longer located at the position corresponding to the blockingpart 86 of the blocking member 53 (the blockingfeature 72 of the actuating member 52no longer blocks the blockingpart 86 of the blocking member 53), such that the control member 55 (and the blockingmember 53 and the base 57) can be further moved relative to the actuatingmember 52 from the close position R' to the over-push position P' along the first direction D1. That is, thesecond furniture part 24 can be moved from the close position R to the over-push position P. - As shown in
FIG. 25 andFIG. 26 , when the control member 55 (and the blockingmember 53 and the base 57) is moved relative to the actuatingmember 52 from the close position R' to the over-push position P' along the first direction D1 (that is, thesecond furniture part 24 is moved from the close position R toward the over-push position P along the first direction D1), the blockingpart 86 of the blockingmember 53 can pass by the blockingfeature 72 of the actuatingmember 52, and thefirst guiding feature 70 of the actuatingmember 52 further enters thelinear section 98b of thesecond guiding feature 96 of thecontrol member 55. In other words, thesecond furniture part 24 can be moved from the close position R to the over-push position P along the first direction D1 in order to allow the openelastic member 32 to release the opening force. As such, thesecond furniture part 24 can be driven by the opening force to move to the open position E along the second direction D2. (Please also refer toFIG. 20 . For simplicity, no further illustration is provided.) - Preferably, as shown in
FIG. 27 , when thefirst guiding feature 70 of the actuatingmember 52 enters thelinear section 98b from theinclined section 98a of the second guiding feature 96 a predetermined traveling distance, the blockingmember 53 is in the second state S2, and the control member 55 (and the base 57) is moved to the close position R' relative to the actuatingmember 52 along the first direction D1. Wherein, the actuatingmember 52 and the abuttingmember 92 contact each other, in order to press the auxiliaryelastic member 94 to accumulate an elastic force. - As shown in
FIG. 27 andFIG. 28 , when the auxiliaryelastic member 94 releases the elastic force to the abuttingmember 92, a counterforce is correspondingly generated along the second direction D2, such that the gap G can be kept between the actuatingmember 52 and the blockingmember 53 for assisting the blockingmember 53 in moving from the second state S2 to the first state S1. (Please also refer toFIG. 24 andFIG. 25 . For simplicity, no further illustration is provided.) - The present invention further provides a control method for the
furniture system 20. The control method comprises the following steps: - Step S10:
- Provide the blocking
member 53 and thecontrol member 55 mounted to thebase 57, wherein the blockingmember 53 is movable between the first state S1 and the second state S2 relative to thebase 57, and thecontrol member 55 is movable the first control state C1 and the second control state S2 relative to thebase 57; - Step S20:
- Provide the actuating
member 52; - Step S30:
- Move the blocking
member 53 from the first state S1 to the second state S2 to be blocked by the actuatingmember 52 when thesecond furniture part 24 is moved from the open position E toward the close position R along the first direction D1, in order to prevent thesecond furniture part 24 from being moved from the close position R to the over-push position P; and - Step S40:
- Move the blocking
member 53 from the second state S2 to the first state S1 without being blocked by the actuating member 52 a period of delay time after the actuatingmember 52 drives thecontrol member 55 to move from the second control state C2 to the first control state C1, in order to allow thesecond furniture part 24 to be moved from the close position R to the over-push position P. - Therefore, the present invention is characterized in that:
- 1. When the
second furniture part 24 is moved relative to thefirst furniture part 22 from the open position E to the close position R along the first direction D1, theprotection device 34 can be used to prevent thesecond furniture part 24 from being further moved from the close position R to the over-push position P along the first direction D1, in order to prevent the openelastic member 32 from releasing the opening force. In other words, thesecond furniture part 24 can be prevented from being unintentionally opened relative to thefirst furniture part 22 along the second direction D2. - 2. The blocking
member 53 is correspondingly in the first state S1 or the second state S2 in response to thecontrol member 55 being in the first control state C1 or the second control state C2, in order to allow thesecond furniture part 24 to be moved from the close position R to the over-push position P or prevent thesecond furniture part 24 from being moved from the close position R to the over-push position P.
